Critical Metals Wins Greenland Approval for Tanbreez Rare Earth Mine

Greenland Resources Inc. has collected more than eight tonnes of drill core and fourteen tonnes of saline and fresh water from its Malmbjerg ore body in Greenland for a by-product test program backed by a non-repayable contribution from the government of Canada. The materials are expected to arrive at SGS Lakefield in Ontario around October 12, and the test program, which aims to verify metallurgical recoveries and concentration grades, will continue until March 2028. The work falls under the Malmbjerg Project Molybdenum Optimization, and Magnesium and Rare Earths By-product Feasibility Study, which received $7 million from Natural Resources Canada's Critical Minerals Research, Development and Demonstration Program. The company noted that China accounts for approximately 69% of global rare earth element production and 89% of global magnesium production, with the EU sourcing 97% of its magnesium from China and US net import reliance on magnesium exceeding 75% of consumption in 2025. The program covers characterization of ore samples and process water, optimization of molybdenum flotation under fresh and saline water conditions, and evaluation of magnesium and REE recovery pathways, with each program potentially advancing to continuous pilot-scale testing.

Land and Houses Fund Management, or LH Fund, has opened the initial public offering of the LH Critical Materials open-ended fund (LHCRITMAT) from October 6 to 14, 2026, with a risk level of 7. The fund invests in the master fund, the Sprott Critical Materials ETF (SETM), at an average of no less than 80% of net asset value per fiscal year. Monarat Padungsit, Managing Director of LH Fund, said critical minerals are becoming a strategic raw material for the modern world, driven by their necessity for energy production, transmission and storage, as well as the defense and aerospace industries. The master fund is passively managed, tracking the Nasdaq Sprott Critical Materials Index, which selects stocks that derive at least 50% of revenue or assets from the critical minerals business, caps each security's weight at no more than 4.75%, and reviews index constituents every six months. Its key highlight is diversification across nine critical mineral groups through a single fund, with copper at 26.6% and uranium at 25.2%, followed by lithium, silver and rare earths, as of June 30, 2026. The master fund's portfolio has more than 77% combined exposure to companies listed in Canada, Australia and the United States, in line with the trend of supply chain diversification away from China. The master fund returned 60.33% over the past year and an average of 18.36% per year since inception, as of August 31, 2026. On the demand side, China accounts for as much as 90% of global rare earth processing and refining, while Japan relied on imports from China for 63% of its rare earths in 2024. The United States Geological Survey announced its 2025 national critical minerals list of 60 items, 10 more than the previous list. The IEA estimates global power grid investment in 2026 at about 550 billion US dollars, up nearly 20% from the previous year, with nuclear power capacity under construction totaling 78 gigawatts across 15 countries. NATO members aim to raise defense budgets to 5% of GDP by 2035. On the supply side, constraints remain: capital spending by critical minerals mining companies fell 9% in 2025 and exploration budgets dropped 10%. The IEA estimates that by 2035, mines worldwide may produce 30% less copper than needed and 40% less lithium, requiring about 500 billion US dollars in new mine investment by 2040.

American Rare Earths has unveiled an updated Scoping Study for the Cowboy State Mine outlining a larger development concept for Halleck Creek, CEO Mark Wall said. The study evaluates a 4.5-million-tonne-per-year operation with a projected mine life of 26 years, generating an estimated after-tax net present value of approximately US$1.07 billion at an 8% real discount rate. Initial capital is estimated at approximately US$900 million, comprising roughly US$690 million in direct capital and US$210 million in contingency, with the updated study applying a 30% contingency allowance to direct capital versus 20% in the company's 2025 study. Modelled average annual production of neodymium-praseodymium oxide has increased from approximately 1,800 tonnes to 2,500 tonnes, and a separate closure cost provision of approximately US$56 million has been included at the end of the projected mine life. The development concept combines mining, comminution and mineral concentration at the Cowboy State Mine with a separate hydrometallurgical refinery planned for the Wheatland or Laramie area of Wyoming, as the company aims to establish a domestic supply of rare earth oxides and advance technical work to connect those materials with downstream U.S. production of rare earth metals and permanent magnets.
